Structure and Meaning in Mathematics: Divergent Roles of Syntax and Meaning-Based Language in Autism.
Article in Journal of autism and developmental disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeMathematical reasoning in adolescence relies on higher order language abilities, yet little is known about how specific language domains support mathematical performance in autistic adolescents, especially in morphologically rich languages such as Hebrew. This study examined the roles of syntax and pragmatics in mathematical performance among Hebrew-speaking autistic and typically developing (TD) adolescents.
methodParticipants were 67 adolescents (31 autistic, 36 TD; ages 12-19). Syntax and pragmatics were independently coded from a Definition Task, and mathematics was assessed across procedural thinking, arithmetic comprehension, and algebraic technique. Because groups differed in morphology, this variable was entered as a covariate. Group differences were examined using ANCOVA and mean-rank ANCOVA. Spearman correlations tested within-group associations, and moderation analyses assessed whether group affiliation moderated language-mathematics relationships.
resultsAutistic adolescents performed significantly lower than TD peers in procedural thinking, algebraic technique, and total mathematics, whereas syntax and pragmatic definition scores did not differ once morphology was controlled. Among TD adolescents, syntactic ability was positively associated with all mathematical measures. In contrast, among autistic adolescents, pragmatic ability-but not syntax-was positively associated with mathematical performance. Moderation analyses confirmed that the strength of language-mathematics associations differed by group.
conclusionsLanguage supports mathematical reasoning in adolescence, but the relevant pathways differ across developmental profiles. TD adolescents appear to rely primarily on syntactic-structural processing, whereas autistic adolescents rely more on meaning-based pragmatic abilities. These findings highlight the importance of examining specific language domains rather than composite scores and support tailoring mathematics instruction to the linguistic strengths of autistic learners.
